The homepage has high-level information, and the tabs at the top allow for deeper dives.

The dashboard is in an early beta stage of testing, so if there is anything I can add to make this tool more useful for you, please reach out to me with any feedback (Ben@cal-cca.org)

COVID Impacts

Current Impacts

To create these figures, we take hourly data from the last five years and create a counterfactual of demand prior to the COVID-19 outbreak using weather, seasonal, and daily normalizations. The method uses a machine learning technique designed for prediction. With the prediction, we take actual demand minus the prediction to create a percent change since the COVID-19 outbreak. The result is plotted through time to visualize the dynamic impact resulting from COVID-19/shelter-in-place.
